Benefits of technology

[0006]The present invention relates to a method of auditory manipulation of an auditory stream for enhancement of language processing in an autism spectrum disorder (ASD) individual. A processor receives the auditory stream, where the auditory stream includes an acoustic stimulus perceptually representing an object. An acoustic manipulation parameter is selected for a predetermined acoustic detail characteristic. The predetermined acoustic detail characteristic is associated with the ASD individual and based on a measured language processing capability of the ASD individual. The processor modifies the auditory stream based on the selected acoustic manipulation parameter. The modification to the auditory stream reduces the predetermined acoustic detail characteristic while preserving a lexicality of the stimulus, such that the reduced acoustic detail characteristic enhances perception of the object by the ASD individual even when the stimulus includes two or more acoustically distinct stimuli each perceptually representing the object. The modified auditory stream is output to the ASD individual via at least one loudspeaker.
[0007]The present invention also relates to a device for auditory manipulation of an auditory stream for enhancement of language processing in an autism spectrum disorder (ASD) individual. The device includes an

Embodiment Construction

[0015]As discussed above, ASD individuals have difficulty abstracting perceptual objects from acoustically distinct but conceptually identical stimuli. This difficulty may be caused by impairment in the basic building blocks of language function, by the creation of redundant representations of the same “object”, colored by too much attention to irrelevant acoustic detail.

[0016]Evidence for such failure may be seen in electrophysiologic responses (e.g., recorded by magnetoencephalography (MEG), a type of functional brainwave mapping which allows depiction of brain function in space and time) indicating lack of “clustering” of responses around perceptual objects, a heightened sensitivity to acoustic (but not linguistic) differences and a general delay processing auditory input (secondary to exerting too much effort processing minor acoustic differences). Priming effects (both electrophysiologically and behaviorally) would also indicate heightened attention to “irrelevant” details, pre...

Abstract

Methods and devices can enhance language processing in an autism spectrum disorder (ASD) individual through auditory manipulation of an auditory stream. The auditory stream is received and includes an acoustic stimulus perceptually representing an object. An acoustic manipulation parameter for a predetermined acoustic detail characteristic is selected. The predetermined acoustic detail characteristic is associated with the ASD individual and is based on a measured language processing capability of the ASD individual. The auditory stream is modified based on the selected parameter, to reduce the predetermined acoustic detail characteristic while preserving a lexicality of the stimulus, such that the reduced acoustic detail characteristic enhances perception of the object by the ASD individual even when the stimulus includes two or more acoustically distinct stimuli each perceptually representing the object. The modified auditory stream is output to the ASD individual via at least one loudspeaker.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims priority to U.S. Provisional application Ser. No. 61 / 865,293 entitled DEVICE FOR ENHANCEMENT OF LANGUAGE PROCESSING IN AUTISM SPECTRUM DISORDERS AND RELATED LANGUAGE IMPAIRMENTS, filed on Aug. 13, 2013, which is incorporated fully herein by reference.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH[0002]The present invention was made with government support under Grant No. R01HD073258 awarded by the National Institutes of Health.
